**Boo** is a cross-platform windowing and event manager similar to
|
2016-03-24 08:54:54 +00:00
|
|
|
SDL or SFML, with additional 3D rendering functionality.

|
|
|
The primary focus of Boo is 2D/3D rendering using polygon-rasterization
|
2015-11-11 23:29:25 +00:00
|
|
|
APIs like OpenGL or Direct3D. It exposes a unified command-queue API for
|
|
|
|
|
calling the underlying graphics API.
|
|
|
|
|
|
|
|
|
|
The only per-platform responsibility of the client code is providing the
|
|
|
|
|
shaders' source. Drawing, resource-management and state-switching are
|
|
|
|
|
performed using the unified API; these may be written once for all platforms.
|
|
|
|
|
|

|
|
|
Boo also features a unified audio API for mixing voices and performing variable
|
2016-03-25 08:54:00 +00:00
|
|
|
sample-rate-conversion. All audio computation occurs on the CPU, synchronously 'pumped'
|
2016-03-24 08:54:54 +00:00
|
|
|
by the client each frame-iteration.
|
|
|
|
|
|

|
|
|
Client code is entered via the `appMain` method supplied in a callback object.
|
|
|
|
|
This code executes on a dedicated thread with graphics command context available.
|
|
|
|
|
The API may be used to synchronize loops on the client thread with the display
|
|
|
|
|
refresh-rate.
